Wing vein Pts of forewing slightly dark. Dorsal ABD TERG I–VII with a pair of spinal setae on small elevations, ABD TERG VIII with a pair of spinal setae, ABD TERG margin I-IV with a single seta on cone-shaped marginal tu bercle, 4th marginal tubercle 0.04-0.05mm.

Distribution.

This species is originally distributed in East Asian countries; Korea ( Paik 1965), China ( Qiao and Zhang 2004), Japan ( Higuchi 1968), and eastern Russia ( Blackman and Eastop 2017). It has been introduced into Europe ( Pons and Lumbierres 2004, Stroyan 1964), and USA (California) ( Clarke 1903). However, the recent DNA barcoding result revealed that European populations are genetically different from Asian populations ( Lee et al. 2017).

Host plants.

Arundinaria spp., Bambusa spp., Phyllostachys spp., and Sasa spp. ( Poaceae ).
